This invention relates to garbage incinerators.

novel form of conical hopper or grate which is so constructed that it rests upon lugs cari ried by the outer casing of the hopper and which permits the passage of the products of combustion fronrthe burner into all portions of the lower surface of the supported garbage, and which consequently permits ready and quick drying of thevgarbage.

Further objects are to provide a novel form of garbage incinerator in which the burner and the pivotally mounted supply pipe are cast integral, and the burner so constructed that it cannot become clogged or in any way obstructed .by the garbage which it supports, but which instead is provided with overhanging portions which shield the 2 fuel or mixture apertures or outlet apertures of the burner.

Further objects are to provide a garbage incinerator in which the conical open work hopper and an annular burner together form a grate, and in which a flat distributor is mounted above the burner so that the entire charge of garbage is heated in a very intimate manner by the products of combustion, and in which an apertured colander is pro ,=vided for permitting steaming of the garbage during drying, and the outward passage of the steam andvapors from the garbage prior --to the burning stage, so that a very quick operating incinerator 'is pro- It has been found with incinerators as heretofore constructed'that they are sometimes placed upon a wooden floor and consequently scorch or burn the 'floor. This in- 140 vention isdesigned to'overcome the defect noted above, and further objects of this invention are to providea novel form of incinerator whichis so constructed that it may be placed directly upon the floor without danger of burning the floor, which is provided with short supporting legs permitting circulation; ofair beneath the bottom ofthe incinerator, and which is equipped with lugs ,which space the ash pan from the bottom of th incinerator, thus giving a double air edge.

I space between the hot portionsof the incinerator and the floor. Objects of this invention areto provide a or lever for dumping the grate. V V

Referring to the drawlngs, t will be seen thattheincinerator consists of a cylindrical outer shell 1 preferably of wrought iron, which is bolted to a bottom2 and an upper cover 3. The bottom and the cover are provided with annular flanges, as shown in Figure 1, to facilitate the attaching :of the shell 1.

Within this outer shell 1, a perforated colander 4is positioned and carried by a plurality of lugs 5 secured to the inner side wall of the shell 1; In addition to this, these lugs prevent rotation of the colander, as they pass through notches in the loottom If desired, spacing sleeves 6 may be positioned between the colander at and the shell 1 and may carry clampingbolts 7, as shown in Figure 1. The upper portion of the colander is held in correct position by means of a plurality of lugs 8 integral with the upper or top portion 3.

The top portion is provided with an outlet or flue opening 9 and with an annular flange surrounding such opening and is provided with a suitable form of removable cover 10 to'permit ready dumping of the garbage into the incinerator. c

The grate consists of a conical structure formed of a plurality of downwardly and inwardly converging spaced grate bars 11 whichare integrally joined to an upper ring 12 and a lower ring 13. 'The upper ring rests upon the top of the lugs 5 and is thus adequately supported at spaced points. The lower ring 13 is positioned around the burner '14: and is spaced therefrom asshown Above the burner, a flame distributor 15 is provided. The flame distributor is hollow and is provided with a plurality of apertures 16 through which the products turesl'S and-inner apertures 19 for the dis- 7 charge of the fuel or mixture. The burner is also provided with an overhanging upper annular plate which prevents any.

garbage from packing against the discharge apertures of the burner. The burner 1s made integral w1th a supply plpe 21 and an arm in alignment with the pipe 21, as

shownin Figure 3. The supplypipe 21 is preferably provided with an annular groove 22 into 'which a lug 23 carried by a plate 24 projects and thus prevents axial motion ofthe pipe, whilepermitting rocking motion. Preferably, a pair of plates 24;.are provided one beingshown in Figer shell 1.

ure 2, to facilitate the assembling of the device. Preferably,

the rod or arm 25 projects through a plate 26 carriedby the outwith a flattened portion to which the forked end 27 of an operating or tilting handle 28 The handle is provided with a fin 29 which normally fits behind the lip or stop 30, as shown in Figure 3. It is so positioned that the weight of the burner 14, which is offset with reference to the axis of the pipe and rod, urges thefin 29 into engagement with the lug'30. In order to dumplthe burner or rock it into the dotted line position, all that is necessary is to rock the lever 28 to a slight extent (in a counter clockwise direction to free it from the lug 30. Thereafter,the'lever is rockedtowards the observer, as viewed in Figure 3, and

thereafter rocked in a clockwise direction.

This permits ready dumping of the ashes and incombustible portionofthe charge after burning has been completed.

It is to be noted from Figure 2 that the upper annular plate 20 of the burner is provided with a pluralityof radial ribs or fins 31 which aid in spacing the charge upwardly and also aid in securing a free circulation of the products of. combustion b around all portions of the bottom of the charge. 'The bottom 20f the incinerator is provided with acplurality of downwardly extending legs 32 adapted to rest upon a floor or other supporting-surface '33 (see 71 l this bottom is provided with upwardlyproand it isto be observed also that jecting, lugs 3t upon which an ash pan 85 frestsJ This ash'pan may be provided with a handle 36. It is spaced from'the side wall or shell. f the device and also from the bottom, and thus provides a dead air .space36 between the bottom and the ,ash

pan. Further, an .air space is provided he it may be.

This rod or bar is provided in considerable detail, such intended as illustrative rather than limiting ends of said portion, a tilt ngburner withln said second a plurality .face of the extending above the upper edge of said sec- 1 and having tween the bottom 2 and the floor 33, so that free circulation of air is permitted, and these parts are thus kept cool. There is thusa double air space-between the heated portions of the apparatus and the'floor and consequently scorching of the floor cannot occur, j Y a The bottomis provided with a "door 37 which may be opened to permit the removal of the ash pan, as required.

It will, be. seen. thatia novel form of garbage incinerator has been provided in which a very intimate and extensive contact surface. is afforded between the heated products of combustion and the charge of garbage, and-in which it is impossible to clog the burner by the garbage, however soft and wet It will beseen also that the device is so constructedthat ready dumping of the inconibustible portions of the garbage after firing, may be secured.

Further, it is to be noted that the device is simple in construction and may be readily produced and assembled.

Although the. invention has been-described description is as the invention may be variously embodied and as the scope of such invention is to be in thelower end ofthecolander forsu pporting said colander within the shelhmeans for normally spacing ,the colander from the shell, a conical grate formed with a plurality of inwardly converging slanting bars and having. an opencentral portion,aring connecting the bars at their upper ends and resting on thelugs which support :the colander, asecond ring connecting the lower bars around the open central ring for closing. the lower portion of .the

grate, a'plate upon the upper side of the urner with its edges overhangingthe same, of radial ribs upon the upper plate with their upper edges ond ring and a hollow, perforated :fiame distributor located above said grate.

2. A garbage incinerator comprising an outer-shell, aperforated colander positioned within and spaced from said outer shell, a plurality of lugs carried the outer shell their inner ends "extending through notches in :the'lOwer edge of the colander forsupporting the colander within the shell, ;a conical grateformed of a plurality of, downwardly converging slanting bars and having an open central portion and an annular upper ring arranged in the colander and supported by said lugs, a tilting burner closing the lower portion of said grate and being of annular construction, a top provided with an outlet opening and a feed door and carried by the upper portion of said shell, a plurality of lugs carried by said top and engaging the upper end of said colander, and a hollow, perforated flame distributor located above said grate.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee,

' in the county of Milwaukee and State of Wisconsin.
